A payment wearable makes contactless payments simpler. Curve can make the same experience more flexible.
Curve Pay lets you manage several eligible payment cards through one Curve account. Once Curve is connected to your Astari payment ring, bracelet, or keychain, you can choose which underlying card funds your purchases without changing how you pay at the terminal.
You simply tap your wearable. Curve handles the selected payment card behind the scenes.
What Is Curve Pay?
Curve Pay is a digital wallet and card service that brings supported debit and credit cards together in one account.
Inside the Curve app, you can add eligible cards, select the card you want to use, and manage your payments from one place. Availability depends on your country, card issuer, Curve plan, and Curve’s current eligibility rules.
When Curve is connected to an Astari wearable, it acts as the bridge between the wearable and the payment card selected in your Curve account.

Why Use Curve With a Payment Wearable?
An Astari wearable already allows you to pay without taking out your bank card or unlocking your phone. Curve adds more control over the payment source behind that tap.
You might use a personal card for everyday purchases, a travel card while abroad, a business card for work expenses, or a rewards card for selected purchases.
You continue paying with the same ring, bracelet, or keychain while managing your preferred card inside Curve.
This combination is especially useful for people who want to pay without carrying a wallet or phone, but still want access to more than one payment card.
How Curve Works With an Astari Wearable
Astari wearables use passive NFC technology. They have no battery, require no charging, and do not need a Bluetooth connection during payment.
Once activated, the wearable communicates with a contactless payment terminal in a similar way to a contactless bank card.
Curve sits behind this payment experience. Your eligible cards are added to Curve, Curve is connected to your Astari wearable, and you select the card you want Curve to use. At the terminal, you simply tap your wearable and Curve routes the purchase to your selected card.
The terminal interaction remains the same regardless of which underlying card you select.
How to Connect Curve to Your Astari Wearable
You only need to connect Curve to your wearable during the initial setup.
- Download the Curve app and create an account.
- Add your eligible debit or credit card to Curve.
- Complete any verification or activation requested by Curve.
- Open the Manage Mii app.
- Follow the instructions to connect Curve to your Astari payment ring, bracelet, or keychain.
- Complete the activation process.
- Test the wearable at a contactless payment terminal.
For detailed wearable instructions, follow the Astari setup guide. You can also review the currently supported connection options on our Supported Banks page.
Card eligibility and Curve features can vary by country and subscription. Check the latest information in the Curve app before beginning setup.
Can One Payment Wearable Use Multiple Cards?
Curve allows multiple eligible payment cards to be managed through one account. Your Astari wearable remains connected to Curve while you select the underlying card Curve should use.
For example, you can select your personal card for everyday purchases and switch to another card for travel or business expenses.
You do not need to reconnect the wearable every time you change the selected card. The selection is managed within Curve.

Changing the Card After a Payment
Curve’s Go Back in Time feature can move an eligible purchase from one connected payment card to another after the transaction.
This can be useful when you accidentally select the wrong card, want to move a business expense to a company card, or prefer to use another card for a particular purchase.
Limits, eligible transactions, and the available time window depend on your Curve subscription and current terms. Curve documents the latest conditions in its Go Back in Time guide.
A Practical Option When Your Bank Is Not Directly Supported
Not every bank supports a direct connection to payment wearables.
For many customers, Curve provides another route by connecting an eligible existing bank card to Curve and then connecting Curve to the wearable.
This may allow you to use an Astari payment ring, bracelet, or keychain without changing banks. Compatibility is not universal, so check both Curve’s current card requirements and Astari’s Supported Banks page before setup.
Using Curve and an Astari Wearable While Travelling
A payment wearable can be particularly convenient while travelling. You can make contactless payments without repeatedly taking your phone, wallet, or bank card out in busy locations.
Curve may also help you manage different cards or currencies while keeping the payment experience consistent. Travel fees, exchange allowances, and benefits depend on your country and Curve plan, so review the applicable terms before travelling.
The Astari wearable itself does not need a battery, mobile signal, or Bluetooth connection during payment.

Is Using Curve With a Payment Wearable Secure?
Curve keeps underlying card details behind the Curve payment credentials and provides account controls through its app. Curve also offers security features such as card freezing and transaction notifications. Read Curve’s current security information.
Astari wearables use secure contactless payment credentials and the established card-network infrastructure used by modern contactless cards.
The wearable does not contain your name or personal account information. Standard card-security rules still apply, and a terminal may occasionally request additional verification.

Why Curve and Astari Work Well Together
Astari keeps the payment moment simple. Curve adds flexibility behind it.
At the terminal, you still make the same natural tap. There is no wearable battery to charge, no app to open, and no phone to unlock.
Inside Curve, you can manage eligible payment cards, choose your preferred card, and use supported tools such as Go Back in Time.
This makes the combination particularly useful for customers who regularly use multiple cards, separate personal and business expenses, travel frequently, or want a payment wearable but do not have direct support from their bank.
